: If the ONT rejects the file, you may need to use a Huawei ONT Firmware Editor to modify the file header to match your device's region or hardware ID.
GPON typically delivers 2.488 Gbps downstream and 1.244 Gbps upstream. EPON offers a symmetric 1.25 Gbps down and up.
This guide applies only to the Huawei EchoLife HG8245H5 variant. Do not attempt this on standard HG8245H, HG8245Q, or HG8245A devices.
This method involves transferring the hw_boardinfo file to your computer, editing it with a GUI tool, and transferring it back.
The Huawei HG8245H5 is a widely deployed GPON ONT. By default, its hardware is locked to GPON standards. However, specific firmware releases from 2021 unlocked dual-mode capability. This allows the device to bridge the gap between competing optical technologies.
refers to a community-developed "cross-flash" method used to repurpose Huawei Optical Network Terminals (ONTs). While the
The key takeaway is that GPON and EPON are not cross-compatible. Therefore, a router or ONT designed for one standard will not function on the network of an ISP that uses the other, unless it is modified or is inherently dual-mode capable.
Instead of forcing a conversion on a GPON-only unit, many modern Huawei models are sold as (dual-mode) devices. These units are designed to automatically detect and adapt to whether they are connected to a GPON or EPON network, eliminating the need for risky firmware "exclusive" hacks.

The Huawei EchoLife HG8245H5 is a widely used Optical Network Terminal (ONT) designed for Fiber-to-the-Home (FTTH) applications, providing high-performance forwarding capabilities for Internet, VoIP, and HD video services. While primarily deployed as a (Gigabit Passive Optical Network) device, many users and ISPs seek to convert these units to support EPON (Ethernet Passive Optical Network) to align with existing infrastructure or to utilize specialized, unlocked firmware for custom configurations.
Flashing unofficial firmware carries a high risk of "bricking" (permanently disabling) your device. Ensure you have the exact firmware file compatible with your hardware version before proceeding. 1. Preparation Identify Hardware : Confirm your model is strictly the Go to product viewer dialog for this item. .
Before diving into commands, it is essential to understand the structural differences. GPON (Gigabit Passive Optical Network) relies on ATM/GEM encapsulation and TDM (Time-Division Multiplexing) for data transmission. Conversely, EPON (Ethernet Passive Optical Network) is based on Ethernet frames and LLID (Logical Link ID) logic. Switching the mode involves changing how the device's PON chipset processes incoming frames.
The ONT will automatically fetch the firmware file from your local TFTP server ( 192.168.100.100 ) and initiate the raw write process. Post-Flash Verification and EPON Configuration
